Hi Mikko,

I am using the latest DLMS library to test IS15959-2 meter.

Firstly, I uploaded the firmware version 1.0. Then after uploading 15 blocks out of 600 blocks, somehow communication stopped.

Now I am uploading firmware version 2.0. So as per our logic, first, it reads the last block number from the meter, from where firmware upload stopped. And from that block number firmware upload start.

So In this case, 15 blocks are of 1.0 firmware and others are of 2.0. In the verification step, it fails.

dear sir,
i am working on automatic meter reading embedded project. for this i am using GuruxDLMSClientExample source code in c. here what is the format for passing h,p,c,s,r,iIt,a,p,wP,g,S,C,v,T,A,B,D thes values for below function.

Does Gurux.DLMS.Python support SET and Action? do you have example code?

Hi Sir,

We would like to integrate indian standard L&T make ER300P meters using your Gurux DLMS .Net libraries.
As part of the requirement, we need to read only registers (Active Energy, Reactive Energy etc. with use of its OBIS codes) from its RS485 interface using serial communication. And few meters will be looped in daisy chain. so we need to read each meters registers one by one which are in the same loop.

examples provided are with reading of all the objects. but couldn't find a way to read registers alone.

Hello,

Meter has no DST adjustment and always uses UTC+2 timezone. When I read historical data, only the first record has the correct time offset, other rows are affected by local PCs settings.

10/23/2020 11:00:00 PM +02:00 //meter timezone, correct
10/24/2020 1:00:00 AM +03:00 //local
10/24/2020 2:00:00 AM +03:00
10/24/2020 3:00:00 AM +03:00
10/24/2020 4:00:00 AM +03:00

If I read the same data on a PC with no DST adjustment I will get the correct data:

Meter time (UTC): 2020-10-25 04:38:13

Hi Mikko,

We are using the latest version of Gurux.DLMS library.

Some times getting an error message in logs "Ciphered failed. Server system title is unknown."

Can you please provide an update on when and why this error comes?

Hi,

I'm trying to get data from Landis Gyr E550 via GXDLMSDirector but it gives me some errors.

hi sir,
I'm new to this work. can i get complete procedure for reading DLMS meter by using guruxclientexample c program.

thanks & regards,
hari

Hi Mikko,

I am very thankful to you for the great support till today, however still have one more query.

Can you please let me know that at what maximum numbers of connections can be handled by Gurux.DLMS? I checked the Gurux.DLMS.Simulator also.

Thanks
Khushbu

Hi,

I'm facing an issue with communication between the meter and the computer (Python). I am using Landis+Gyr E650 and USB converter plugged through RS485. When I'm running the Gurux.DLMS.Client.Example.python using this command "python main.py -S COM4:9600:8None1 -r sn -c 32 -s 1 -a Low -P 00000000" I'm getting log like this https://pastebin.com/TfgH6Esb (I'm running it on windows, all libraries are up to date).
